The video explores Isaac Newton's transformative impact on physics, focusing on his law of universal gravitation. It recounts the famous apple story, illustrating Newton's realization of gravity as a force affecting both terrestrial and celestial bodies. The video details how Newton formulated his gravitational equation, incorporating mass and distance, and how it aligned with Kepler's laws of planetary motion. It concludes with modern applications, such as calculating Martian gravity for NASA's missions, highlighting Newton's enduring influence.
